自定义帖子类型ID问题 - 查询其他帖子类型时

Question

我有一个很复杂的问题要解决，这让我在最后一天左右感到困惑。

基本上，我有两种自定义帖子类型'Sessions'和'Recipes'。这些在WordPress的后端显示正常。

附加到会议的是几个元框，“介绍视频”，“会话视频”，“目标”，“健身水平”和“特色食谱”。

“精选食谱”元框是特殊的，因为它查询WordPress数据库以获取“食谱”自定义帖子类型中的所有帖子，然后使用这些值填充选择框。

现在，您可以从附加的屏幕截图中看到，配方自定义帖子类型的选择框正在提取正确的项目和ID，并且还会保存数据并拉回正确的选择并将其与正确的选项相关联“会话”帖子类型的帖子ID。太好了！

问题出现在帖子中的其他字段中，它们似乎使用第一个食谱ID作为拉取每个字段的数据的值，而不是“会话”自定义帖子类型ID。

现在我可以通过基于特定查询参数编写各种while循环来实现此功能，但这会产生另一个问题。数据保存在正确的位置，但它使用第一个“会话”cpt ID来撤回所有帖子的数据。

现在，我相信它与'recipe'元框创建有关，因为只要你从functions.php文件中删除这个函数及其相关函数，一切都可以正常工作。

我想我应该使用for循环而不是while循环，我现在要尝试这个。

希望你们中的一些PHP大师能够指出我正确的方向。我已经包含了我的functions.php文件和管理员的屏幕截图。欢呼声。

我当然越来越接近这个功能，但它并不完全正确，因为它正在通过相同的标题。

function tfp_recipes_html($post) {

    // Nonce field for some validation
    wp_nonce_field( plugin_basename( __FILE__ ), 'session' );

    $recipeArgs = array(
        'post_type' => 'recipe'
    );
    $recipeQuery = get_posts($recipeArgs);

    $recipeName = get_post_meta( $post->ID, 'recipe_name', true );

    $recipeTitle[] = get_query_var('name');

    echo $recipeTitle;

    ?>

    <select name="recipe_names" id="recipes">
        <option value="null">Select a Featured Recipe</option>
        <?php foreach ( $recipeQuery as $recipe ) : setup_postdata($recipeQuery); ?>
            <option id="<?php echo $recipe->ID; ?>" value="<?php echo $recipeTitle; ?>" <?php if($recipeName == $recipeTitle) echo "selected='selected'";?>><?php echo $recipeName; ?></option>
        <?php endforeach; ?>
    </select>
<?php }

Answer 1

好的伙计们，我使用以下功能解决了我的问题。

function tfp_recipes_html($post) {

    // Nonce field for some validation
    wp_nonce_field( plugin_basename( __FILE__ ), 'session' );

    global $post;

    $recipeArgs = array(
        'post_type' => 'recipe'
    );
    $recipes = get_posts($recipeArgs);

    $recipeName = get_post_meta( $post->ID, 'recipe_name', true );

    ?>

    <select name="recipe_names" id="recipes">
        <option value="null">Select a Featured Recipe</option>
        <?php foreach ( $recipes as $recipe ) : setup_postdata($recipe); ?>
            <option id="<?php echo $recipe->ID; ?>" value="<?php $recipeTitle = $recipe->post_title; echo $recipeTitle; ?>" <?php if($recipeName == $recipeTitle) echo "selected='selected'";?>><?php echo $recipeTitle; ?></option>
        <?php endforeach; ?>
    </select>
<?php }

虽然现在我还有另一个问题，即保存另一个自定义元数据盒。添加元数据的功能是：

function tfp_tips_html($post) {

    // Nonce field for some validation
    wp_nonce_field( plugin_basename( __FILE__ ), 'session' );

    global $post;

    echo $post->ID;

    $tipArgs = array(
        'post_type' => 'tip'
    );
    $tips = get_posts($tipArgs);

    $tipData = get_post_meta( $post->ID, $tipID, true );

    foreach ( $tips as $tip ) : setup_postdata($tip);

        $tipID = 'tip_' . $tip->ID; ?>

        <label for="<?php echo $tipID; ?>">
            <input type="checkbox" name="<?php echo $tipID; ?>" id="<?php echo $tipID; ?>" value="1" <?php if ($tipData == 1) echo "checked='checked'"; ?> />
            <?php $tipTitle = $tip->post_title; echo $tipTitle; ?>
        </label>
        <br />
    <?php endforeach;
}

与配方功能类似，但这会添加每个具有特定ID的复选框。现在保存它的功能是：

function tfp_save_tips($post_id) {

    if ( !current_user_can( 'edit_post', $post_id ) ) { return false; }

    if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) {
        return $post_id;
    }

    if ( ! wp_verify_nonce( $_POST['custom_post_type'], plugin_basename(__FILE__) ) ) return;

    global $tipID;

    add_post_meta($post->ID, $tipID, $_POST[$tipID], true) or update_post_meta($post->ID, $tipID, $_POST[$tipID]);
}

问题是它没有保存数据，而是进入空白页面。

<强> [编辑]

好的，我有数据保存，以及当你回到帖子时正确检查复选框。唯一的问题是它发布到一个空白页面，这是不好的。需要刷新编辑器。

现在使用的功能是：

function tfp_save_tips($post_id) {

    if ( !current_user_can( 'edit_post', $post_id ) ) { return false; }

    if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) {
        return $post_id;
    }

    if ( ! wp_verify_nonce( $_POST['session'], plugin_basename(__FILE__) ) ) return;

    $tipArgs = array(
        'post_type' => 'tip'
    );
    $tips = get_posts($tipArgs);

    foreach ( $tips as $tip ) : setup_postdata($tip);

    $tipID = 'tip_' . $tip->ID;

    endforeach;

    add_post_meta($post_id, $tipID, $_POST[$tipID], true) or update_post_meta($post_id, $tipID, $_POST[$tipID]);
}
